MANUALLY-OPERATED HAY AND STRAW PRESS.

To all whom it may concern:

Be it known that I, EMIDIO PULIFIGI, mechanical engineer, a subject ofthe King of Italy, residing at Magliano Sabino, Italy, have inventedcertain new and useful Improvements in Manually-Operated Hay and StrawPresses, of which the following is a specification.

The object of my present invention is to provide an economical manuallyoperated hay and straw press with simple and multiple lever, adapted tosubstitute the usual costly mechanical and motor presses, andparticularly useful in mountainous regions where motor presses cannot beinstalled and worked but with the utmost difficulties, and the usualhand presses do not give the desired results, the compression beingincomplete and an excessive efi'ort being required.

One of the forms of my new simple and multiple lever hand press isillustrated by way of example in the annexed drawings where:

Figure 1 is a side view of the press, Fig. 2 a section on line aa ofFig. 1, Fig. 3 a detail view of racks, and Fig. 4: a detail view oflocking hook.

Lever 1, Fig. 1, is pivoted on axle 2 of support 3 fixed on a beamsupported by two trestles or jacks, the end of the beam engaging bymeans of a slot the pivot 4 of con necting rod 5, the two latter piecesbeing kept together by a lock 6. Connecting rod 5 is pivoted on thecenter of piston 7 adapted to slide to and fro according to themovements of lever 8.

The compression is effected by simple lever 8 until a sufficientquantity of hay or straw to form a bale has been put into the press, butthis compression being insuflicient, lever 8 is then detached from rod 5and the latter connected to two bars 9 placed symmetrically andpivotally on support 10, by introducing pivot 11 of lever 1 into fork 12of bar 9, and causing the first tooth of the rack of rod 5 to engagepivot 18 on bar 9, thus completing the compression of the bale by piston7 pushing a movable partition wall between the bales which is preventedfrom recoiling by the horizontal rack 14 until it has reached the lasttooth of the latter. The racks lt are placed laterally to- Ward thecenter of the box, Fig. 1, and pivoted to axle 15 to which they areconnected by arms 1616, and form one body with the Specification ofLetters Patent.

two teeth 17, which latter hold the hay or straw when the operation isperformed with the simple lever. Racks 14 instead of being kept in placeby springs are kept in place by weight 18, Fig. 2, acting on the end ofa lever-arm pivoted on support 19.

After one bale has been completed, in order to make others the simplelever is reconstituted by detaching bars 9 from rod 5 and causing lever1 to again engage pivot 4 of rod 5. To'eject the completed bales themovable rear abutment wall kept in place by two stationary teeth and onearticulated tooth 19 (Figs. 1 and a) must be removed, the upper part ofthe press being capable of oscillating on 20 and being shifted at theother end by crank 21 to permit of regulating the ejection of finishedbales.

The machine rolls on wheels rotatable on axle 22 the ends of which areS-shaped. When the machine is working the said axle is in horizontalposition while when it is being transferred the said axle is placed invertical position bearing on the two castiron supports held in place bypegs 23 (Figs. 1 and 2).

Having now fully described my said invention and the manner in which thesame is to be performed, what I claim and intend to secure by LettersPatent of the United States as my invention is:

1. In a manually operated hay and straw press, a frame, a compressorpiston, a connecting rod connected to said piston, a lever pivotallysupported by said frame, means for connecting said lever directly tosaid rod whereby a simple lever action is obtained, a bar pivotallysupported on said frame, means to connect said bar to said rod, andmeans to connect said lever to said bar, whereby a multiple action isobtained.

2. In a manually operated hay and straw press, a frame, a simple leverpivotally mounted thereon, a compressor piston, a connecting rodconnected thereto, means for operatively connecting said lever with saidrod, a forked bar pivotally supported by the frame, means foroperatively connecting said forked bar to said rod, and means carried bysaid lever for engaging the forked portion of said bar, whereby saidsimple lever is transformed into a multiple lever.

3. In a manually operated hay and straw press, a frame, a simple leverwith three unequal arms having one of its arms pivoted provided withteeth adapted to engage said last mentioned pivot.

In testimony whereof I have signed my name to this specification in thepresence of two subscribing witnesses.
